An 80 year old clergy, presented with a 5-day history of left-sided chest pain which was non-radiating but had cough productive of white sputum. No history of haemoptysis, dyspnoea, orthopnoea or paroxysmal nocturnal dyspnoea was elicited. However, a history of smoking 2 cigarettes per day for 10 years was present. He is a known hypertensive on medications,also being managed for diverticulosis ...

INTRODUCTION This prospective study aimed to assess whether use of the subxiphoid acoustic window in transthoracic echocardiography (TTE) can be an accurate alternative in the absence of an apical view to assess hemodynamic parameters. METHODS This prospective study took place in a teaching hospital medical ICU. Over a 4-month period, TTE was performed in patients admitted for more than 24 ho...

A weaving drawdown is a rectangular grid of black and white squares with at least one black and one white square in each row and column. A pattern results from vertical and horizontal translations of the defining grid. Any such grid defines a tiling pattern. However, from a weaving point of view, some of these grids define actual fabrics while others correspond to collections of threads that fa...

A major step in model-based fault diagnosis is the generation of candidate submodules which might be responsible for the observed symptom of malfunction. After the candidates are determined, each subrnodule can then be examined in turn. It is useful to be able to choose the most likely candidate to focus on first so that the faulty parts can be located sooner. We propose here a systematic metho...

This paper presents an object-oriented approach for the implementation of interactive systems. This approach applies the Model-View-Controller (MVC) paradigm, which is modified for the C++ environment. The modified paradigm is called MVC++. In this approach the design of interactive applications starts by constructing an object model that represents the key concepts of the problem domain. This ...

In this paper, we present ViewDF: a declarative framework for incremental maintenance of materialized views over append-only streaming data. The main component of the proposed framework is the View Delta Function (ViewDF), which declaratively specifies how to update a view when a new batch of data arrives. We describe and experimentally evaluate a prototype system based on this idea, which allo...

Visualization: To enable the user to do a visual analysis of film data as comfortable as possible the new software is based on an interactive display realized by VTK [2]. Data is read as tiff images (up to 32bit color depth) and in ASCII format. Interactive funtionality includes zoom, movement and color-window adjustment. The actual color window as well as the coordinates and optical density at...

introduction: poor sensitivity and poor signal to noise ratio because of low injected thallium dose and presence of scattered photons are the main problems in using thallium in scintigraphic imaging of the heart. scattered photons are the main cause of degrading the contrast and resolution in spect imaging that result in error in quantification. thallium decay is very complicated and photons ar...

abstract childhood and adolescence are critical periods for the skeleton. mechanical load has then been shown to be one of the best stimuli to enhance not only bone mass, but also structural skeletal adaptations, as both contributing to bone strength. exercise prescription also includes a window of opportunity to improve bone strength in the late pre- and early peri-pubertal period. there is so...

In this paper, we prove that the general problem of tiling the hyperbolic plane with à la Wang tiles is undecidable.
